IntStream empty()是java.util.stream.IntStream中的方法。此方法返回空的顺序IntStream。
用法:
static <T> Stream<T> empty() Where, T is the type of stream elements, and the function returns an empty sequential stream.
示例1:创建空的IntStream。
// Java code for IntStream empty()
import java.util.*;
import java.util.stream.IntStream;
class GFG {
// Driver code
public static void main(String[] args) {
// creating an empty IntStream, a sequence of
// primitive int-valued elements
IntStream stream = IntStream.empty();
// Displaying an empty sequential stream
System.out.println(stream.count());
}
}
输出:
0
示例2:创建空的LongStream。
// Java code for LongStream empty() method
import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args) {
// creating an empty LongStream, a sequence of
// primitive long-valued elements
LongStream stream = LongStream.empty();
// Displaying an empty sequential stream
System.out.println(stream.count());
}
}
输出:
0
